3.7.3 Advertising Default Routes of a VPN Instance
Context
Do as follows on the S-PE.
Procedure
Step 1 Run:
system-view
The system view is displayed.
Step 2 Run:
bgp as-number
The BGP view is displayed.
Step 3 Run:
ipv4-family vpnv4
The BGP VPNv4 sub-address family view is displayed.
Step 4 Run:
peer { peer-address| group-name } default-originate vpn-instance vpn-instance-name
The default routes of a specified VPN instance are advertised to the U-PE.
If the peer default-originate vpn-instance command is used, the S-PE sends the default route
with the address of the next hop as the local address, regardless of whether a default route exists
in the local routing table.
If you have run the default-route imported command in the BGP VPN view, and then run the
peer default-originate vpn-instance command in the BGP VPNv4 address family view without
importing the IGP routes, the S9300 does not send the default route to the BGP VPNv4 peer.
If the peer default-originate vpn-instance command is configured in the BGP VPNv4 address
family view, and then the default-route imported command is configured in the BGP VPN
instance view, the peer default-originate vpn-instance command takes effect, but the default-
route imported command cannot take effect.
NOTE
Before sending the default routes of the specified VPN instances to a BGP peer or a peer group, ensure
that the BGP peer or peer group is the U-PE.
